(19) At stage 30 both sets of motoneurons were coactivated during the brief discharge that initiated each cycle.
(20) The implications of these findings are discussed with respect to the structure of the yeast and human TATA factors and the possible involvement either of specific TFIID modifications or of coactivators.
Restrictive
Definition:
(a.) Serving or tending to restrict; limiting; as, a restrictive particle; restrictive laws of trade.
(a.) Astringent or styptic in effect.
Example Sentences:

(7) In both experiments, Gallus males were placed on a commercial feed restriction program in which measured amounts of feed are delivered on alternate days beginning at 4 weeks of age.
(8) the class- and specificity-restricted antigen-sensitive units.
(9) Possibilities to achieve this both in the curative and the preventive field are restricted mainly due to the insufficient knowledge of their etiopathogenesis.
